If you have specified that the details of a particular metric should be saved, then the data within the grid cells will be underlined as per the screen-shot below:
If you would like to drill down on these objects, you simply need to single click the cell in question. A popup window will appear listing all objects that have been used in the derivation of the given metric.
Depending upon the metric, you will either see one or two objects listed. For example, in the case of meter reading results, you may see the device/meter as the first entry and then the meter reading order/result as the second entry. Either object can be selected (single click) to then display the object itself. The appropriate transaction will be entered automatically with the correct object.
